Michael Barone‘s latest article for the Washington Examiner dissects Democrats’ spin about the fall elections. 

[T]his Democratic spin sounds a lot like the Republican spin back in the 2006 cycle. If the numbers don’t change too much from 2004, Republicans said then, we can hold on. If the numbers don’t change too much from 2008, Democrats think now, they can hold on.

But the Republicans, as George W. Bush said, took “a thumping” in 2006. And most signs suggest Democrats will take a thumping this year too.

To see why, take a look at the generic ballot question — which party’s candidate will you vote for in elections to the House? The current realclearpolitics.com average shows Republicans ahead by 45 to 41 percent. Ten of this month’s 15 opinion polls asking the question had Republicans ahead; Democrats led in four (twice by 1 percent), and one poll showed a tie.

Keep in mind that the generic ballot question historically has tended to underpredict Republican performance in off-year elections. Gallup has been asking the question since 1950 and has shown Republicans leading only in two cycles, 1994 and 2002, and then by less than the 7 and 5 points by which they won the popular vote for the House in those years.

So the Republicans’ current lead in the generic ballot question suggests they may be on the brink of doing better than in any election since 1946, when they won a 245-188 margin in the House — larger than any they’ve held ever since.
