Hatch in Utah, Rangel in New York, plus more to watch for Tuesday in politics

— -- Voters go to the polls Tuesday for primaries or runoffs in Utah, New York, Colorado, Oklahoma, South Carolina and South Dakota. Two incumbents to watch: Republican Sen. Orrin Hatch in Utah and Democratic Rep. Charlie Rangel in New York's 13 ^th Congressional District.

Hatch faces former state Sen. Dan Liljenquist, who has tea party support, and, based on an independent public poll released Saturday by Deseret News/KSL-TV, Hatch is likely to win. He led Liljenquist among registered voters by 60 to 32 percent.

Rangel faces a tougher contest because of redistricting changes.

President Barack Obama will attend fundraisers Tuesday in Georgia and in the battleground state of Florida, and Mitt Romney will campaign in Virginia, another battleground state, and attend a fundraiser in New Jersey.

Vice President Joe Biden will be campaigning in Iowa — yes, that's a battleground state, too — and first lady Michelle Obama will attend fundraisers in Chicago, including one event with "Glee" star Jane Lynch.

Also worth noting: A group of civil rights leaders will hold a press conference at the National Press Club in support of Attorney General Eric Holder, who faces a contempt of Congress vote in the House of Representatives later this week. Participants will include Leadership Conference on Civil and Human Rights President and CEO Wade Henderson, National Action Network President Rev. Al Sharpton and NAACP President and CEO Benjamin Jealous.

And then there is this: Rielle Hunter's memoir, "What Really Happened: John Edwards, Our Daughter, and Me," is officially released Tuesday. Hunter appears on ABC's "Good Morning America," "Nightline" and "The View" to promote the book
