MICHAEL BARONE: Democrats’ dream of permanent dominance is unlikely.

The 2008-2012 Obama campaign — it never really stopped — did an excellent job of turning out just enough voters to win 332 electoral votes. But Obama carried just 26 states to Mitt Romney’s 24, which is relevant when you look at future Senate elections.

As for House elections, Obama carried only 207 congressional districts to Romney’s 228. That’s partly because Republicans had the advantage in redistricting after the 2010 census.

But it’s also because the Obama core constituencies — blacks, Hispanics, gentry liberals — tend to be clustered geographically in central city neighborhoods in big metropolitan areas. His big margins there helped him carry many electoral votes but not so many congressional districts.

And Obama’s in-your-face liberalism, so apparent in last week’s inaugural speech, antagonized some groups in a way that may hurt Democrats for some time to come.

And you ain’t seen nothin’ yet. Hubris is already here, but nemesis is slouching toward Washington, D.C. (Related item here.)

Barone concludes:

George W. Bush’s 51 percent re-election, with 11.5 million more votes than four years before, got his strategist Karl Rove musing about a permanent Republican majority. That didn’t happen.

Now Barack Obama’s 51 percent re-election, with 3.5 million fewer votes than four years before, has Democrats talking about annihilating the Republican Party. That’s not likely to happen either.

Neither party is very popular, nor likely to be.
