On average, the 17 states Trump identified have been won by the Republican in five of the last nine elections, which seems promising, though that takes us back to 1980 and includes the massive blowout of 1984, so it's really about a split.

The states have been trending away from the Republicans, though. Ronald Reagan won at least 15 of them both times he ran. George H. W. Bush won 14. Each time he won, George W. Bush won 11. In 2008, John McCain won only three -- one of which was his home state.

You can see that cluster where Obama's margin was the smallest: Pennsylvania, Colorado, Virginia, Ohio and Florida. Flip all five of those and Trump wins by 52 electoral votes. This isn't too shocking. If you weren't aware that Ohio and Florida were key presidential election states, we suspect that you're just a hair shy of being able to get your learner's permit.

The problem for Trump at this point is that he's already trailing in many of those states. Hillary Clinton is outperforming Obama's 2012 numbers at this stage of the race everywhere but Ohio, New Hampshire and Pennsylvania among the states where we have data from theRealClearPolitics polling average. While she's trailing Obama's lead in those states, she still leads in all three.

Part of this is because her campaign is already out there campaigning. At this point, Clinton (and her allied PACs) is outspending Trump (and his) by a 46-to-1 margin in battleground states, according to NBC News' Mark Murray.

To understate it a bit: Such an imbalance has not proven to be a winning campaign strategy in the past.

More bizarre still is that the Journal reports Trump's campaign manager as insisting that the team still thought they had a shot in New York and California. A Field Poll conducted in California this month showed Clinton leading Trump by 30 points, a bigger margin than Obama saw in 2012 in any state besides Hawaii or Vermont.

Or we can put it another way. Here's the voting trend for California and New York.
