Monday in politics: Romney, Ryan in N.H., Dems announce convention speakers, and more

Mitt Romney and Paul Ryan will campaign together Monday in New Hampshire. The main event will be a "Victory Town Hall" in Manchester. A topic that is certain to come up: Medicare.

The campaign had originally indicated that Romney and Ryan would not appear together until the Republican National Convention in Tampa, Fla., which begins on Aug. 27.

President Barack Obama campaigned in New Hampshire on Saturday, and targeted Romney's personal tax rate. He said Romney chose Ryan as a running mate because Ryan's budget plan would reduce his tax burden to less than 1 percent each year.

New Hampshire, with only four electoral votes, is the smallest of the battleground states.

The Democratic National Committee will officially announce convention speakers on Monday, The Washington Post reports. Included: Chicago Mayor Rahm Emanuel, Obama's former White House chief of staff; Sen. John F. Kerry; Massachusetts Gov. Deval Patrick; and former Virginia governor Tim Kaine.

In other political convention news, Ann Romney on Monday is expected to be named the headliner for the first night of the Republican convention, CNN reports, and Republican National Committee Chairman Reince Priebus and Republican National Convention CEO William Harris will unveil the stage and podium for the GOP convention.

Back at the White House, Obama will be interviewed Monday by local TV anchors from Florida, Virginia and California, and first lady Michelle Obama will host the first kids state dinner.

And then there is this: It's Rep. Ron Paul's birthday. The three-time candidate for the presidency turns 77.
