When the deficit's "under control", will the Conservatives be able to resist deficit-funded tax cuts?

There's no reason why they should even try.

Matt Yglesias asks what could be an existential question for conservatives on both sides of the Atlantic:

This is the question for John Boehner and Paul Ryan whenever they do unveil their balanced-budget plan: Why not make taxes lower instead of balancing the budget? The budget will, presumably, cut spending down to a level that conservatives think is appropriate. Say that sums up to 18 percent of GDP. Well if you're spending 18 percent of GDP and 18 percent of GDP is the right amount to spend, then why is it better to raise 18 percent of GDP in taxes rather than raise 16 percent and borrow the rest?

For the time being, in Britain and America, rhetoric about "getting the deficit under control" and about "shrinking the size of the state" are pointing in the same direction. Both are reasons for the massive spending cuts which the Conservatives and Republicans have attempted to enact.

Most of the attacks on the false connection between those two arguments have been focused on the "shrinking the state" part of the equation. That is, questions like "if we're trying to reduce the deficit, why aren't we raising taxes on the rich/on bankers/on financial transactions" are appropriate for exposing the drive for deficit reduction as a sham, driven largely by ideology.

But what if, instead, we accept — hypothetically — that the size of the state had to be shrunk. Eventually, spending would be "under control", whatever that means for them, and the choice would become whether taxes ought to be at the same level. Why, all things considered, would it be bad if they weren't? Yglesias asks:

Is it because a 2 percent of GDP budget deficit would be inflationary? Is it because an inflation-targeting central bank faced with a 2 percent of GDP budget deficit would be forced to peg short-term interest rates at a high level? What's the problem, exactly, that the budget balancing solves once we've stipulated that spending has been cut to an appropriate level?

Of course, in the political world, we would be unlikely to get such a clear answer to that question. Rhetoric about a "maxed-out credit card", "paying off the country's mortgage" or "unsustainable budget deficits" — where "sustainable" is never defined — dodges the fact that the macroeconomics of small persistent budget deficits in a country which controls its own currency are relatively settled: it's fine. And chances are that if the Conservatives do manage to get the deficit down, and cling on to power through 2015, then they will do the obvious thing, and enact deficit-funded tax cuts.

But getting a straight answer to that question from the economically minded people who call for swingeing spending cuts now would be interesting indeed.

How Jim Murphy's mistake cost Labour - and helped make Ruth Davidson

Scottish Labour's former leader's great mistake was to run away from Labour's Scottish referendum, not on it.

The strange revival of Conservative Scotland? Another poll from north of the border, this time from the Times and YouGov, shows the Tories experiencing a revival in Scotland, up to 28 per cent of the vote, enough to net seven extra seats from the SNP.

Adding to the Nationalists’ misery, according to the same poll, they would lose East Dunbartonshire to the Liberal Democrats, reducing their strength in the Commons to a still-formidable 47 seats.

It could be worse than the polls suggest, however. In the elections to the Scottish Parliament last year, parties which backed a No vote in the referendum did better in the first-past-the-post seats than the polls would have suggested – thanks to tactical voting by No voters, who backed whichever party had the best chance of beating the SNP.

The strategic insight of Ruth Davidson, the Conservative leader in Scotland, was to to recast her party as the loudest defender of the Union between Scotland and the rest of the United Kingdom. She has absorbed large chunks of that vote from the Liberal Democrats and Labour, but, paradoxically, at the Holyrood elections at least, the “Unionist coalition” she assembled helped those parties even though it cost the vote share.

The big thing to watch is not just where the parties of the Union make gains, but where they successfully form strong second-places against whoever the strongest pro-Union party is.

Davidson’s popularity and eye for a good photo opportunity – which came first is an interesting question – mean that the natural benefactor in most places will likely be the Tories.

But it could have been very different. The first politician to hit successfully upon the “last defender of the Union” routine was Ian Murray, the last Labour MP in Scotland, who squeezed both the  Liberal Democrat and Conservative vote in his seat of Edinburgh South.

His then-leader in Scotland, Jim Murphy, had a different idea. He fought the election in 2015 to the SNP’s left, with the slogan of “Whether you’re Yes, or No, the Tories have got to go”.  There were a couple of problems with that approach, as one  former staffer put it: “Firstly, the SNP weren’t going to put the Tories in, and everyone knew it. Secondly, no-one but us wanted to move on [from the referendum]”.

Then again under different leadership, this time under Kezia Dugdale, Scottish Labour once again fought a campaign explicitly to the left of the SNP, promising to increase taxation to blunt cuts devolved from Westminster, and an agnostic position on the referendum. Dugdale said she’d be open to voting to leave the United Kingdom if Britain left the European Union. Senior Scottish Labour figures flirted with the idea that the party might be neutral in a forthcoming election. Once again, the party tried to move on – but no-one else wanted to move on.

How different things might be if instead of running away from their referendum campaign, Jim Murphy had run towards it in 2015.
