Props to NYC Mayor Michael Bloomberg:

Joe Baca never saw it coming, and neither did Gloria Negrete McLeod.

But as state Sen. Negrete McLeod replaces Baca in Congress, the dueling San Bernardino County Democrats witnessed first hand the beginnings of a change in gun politics, courtesy of billionaire New York Mayor Michael Bloomberg.

No doubt the strongest gun control advocate on Forbes’ list of the fabulously rich, Bloomberg seized an opportunity to unseat Baca, a pro-gun Democrat, by spending $3.3 million on television and mail attacks. Given his estimated $25 billion fortune, $3.3 million is couch cushion change. But it was three times the sum Baca and Negrete McLeod raised between them. By homing in on a loyal National Rifle Association politician, Bloomberg altered a long-standing element of American politics.

There’s more to this than just guns, McLeod is fairly pro-gun as well, and there is an important bit a few ‘graphs down, that the NRA is basically a partisan organization, where it’s “my cold dead fingers” philosophy now takes a back seat to party:

It skipped Baca’s race, a telling omission. If any candidate warranted NRA support, Baca was that man. In his 20 years in Sacramento and in Washington, Baca rarely if ever wavered from National Rifle Association orthodoxy. There were times when he was the only Democrat who sided with the NRA.

“Joe was a very good friend of the NRA’s,” recalled Steve Helsley, the NRA’s California lobbyist when Baca was in the Legislature.

Baca sought the NRA’s endorsement this year, but said the NRA turned him down because he failed to join Republicans who voted to sanction Attorney General Eric Holder for the ATF’s bollixed Fast and Furious gun investigation, and because he supported Obama’s nomination of Sonia Sotomayor as U.S. Supreme Court justice.

I’m not unhappy about the results.  Baca was a Blue Dog, and he had a long history of directing his campaign funds and those of the House Hispanic Caucus for the benefit of his relatives, and then there is the whole thing of his calling Rep. Loretta Sanchez a “whore” (though not to her face) when she confronted him on this and other irregularities.

Here’s what Blue Dogs and New Dems should take away from this whole story:  If you support lax gun ownership rules, good for you, but do not expect the NRA to do anything, even something as minor as an endorsement when you are running against another Democrat.

They are not your political ally.
