For months now the pro-Romney forces have been trying to thread this needle with independent voters: You had high hopes for Barack Obama; you gave him a chance; he wasn’t up to the task; it’s okay to move on.

(See the hardworking staff’s recent summary – with representative TV spots – here.)

Now comes a new salvo, via our More In Sorrow Than In Anger (MISTIA) desk:

The Super PAC Buyer’s Remorse Tour.

Exhibit A (via the New York Times):

Republicans Intensify Drive to Win Over Jewish Voters

BOCA RATON, Fla. — Using billboards, television advertisements and finely honed voter lists, Republicans here and in other battleground states have intensified an effort to lure a small but potentially significant group of new or wavering voters from President Obama.

Focused on South Florida, Ohio and Nevada, the Republican Jewish Coalition, backed mostly by the casino magnate Sheldon Adelson, a Zionist, has begun spending $6.5 million on an air-and-ground strategy to reach Jewish voters who may view Mr. Obama as unreliable on the question of Israel’s security. Jewish voters, who generally vote for Democrats in big numbers, overwhelmingly supported Mr. Obama in 2008, giving him 78 percent of their vote, according to exit polls conducted by Edison/Mitofsky.

In Florida, where the largest share of the $6.5 million is being spent, one of the group’s most visible messages is along Interstate 95 and the Florida Turnpike, including in Boca Raton and in Broward County, areas with large Jewish populations. A series of red-and-blue billboards lament: “Obama … Oy Vey!!” Then ask, “Had enough?”

Not enough advertising, apparently, given Exhibit B (via Politico’s Morning Score):

RICKETTS SUPER PAC LAUNCHES “WHY I CHANGED MY VOTE” CAMPAIGN: Ending Spending Action Fund, the conservative super PAC backed by billionaire investor Joe Ricketts, is making an initial $1.5 million buy as part of the pledged $10 million campaign against Obama with two ads that will debut nationwide today on cable. A 30-second spot features former Alabama Congressman Artur Davis complaining that Obama pushed through his health care law without a single Republican vote. A 60-second spot features three middle-aged women who voted for Bill Clinton, Al Gore and Barack Obama saying they’re voting for Romney this election.

Look for more on the MISTIA patrol in the few weeks left until the election.
