Eleven states went to the polls on Tuesday to choose their leaders. Forty-four states were also choosing legislatures and several states also had competitive ballot initiatives.

FOX News projects four incumbent governors winning re-election: North Dakota Republican Gov. John Hoeven (search), Vermont Republican Gov. James Douglas (search), Democrat Mike Easley (search) of North Carolina, and Democrat Ruth Minner (search) of Delaware.

FOX News also projects that Democrat Joe Manchin (search) has won the seat to replace retiring Democratic Gov. Bob Wise in West Virginia. Republican Jon Huntsman (search) wins in Utah, beating out Democrat challenger Scott Matheson Jr. Democrat Brian Schweitzer (search) defeated Republican Bob Brown in Montana.

Incumbent governors in Indiana and New Hampshire have both lost their re-election bids to challengers, FOX News projects. Republican candidate Mitch Daniels (search) is the winner in Indiana, unseating Democratic incumbent Joe Kernan. Democrat John Lynch (search) beat out current Gov. Craig Benson in New Hampshire.

FOX News projects that Colorado's voters rejected Amendment 36 (search), which would have proportioned the state’s electoral votes by congressional district as opposed to the current winner-take-all approach. Therefore Bush, who won the state, will get all of its nine electoral votes.

California voters passed Proposition 71 (search) in favor of establishing an institute for stem cell research. The measure provides up to $3 million in funding for the project.

The nationwide debate over gay marriage reached the ballot box in 11 states. In a resounding, coast-to-coast rejection, voters in 11 states approved constitutional amendments Tuesday limiting marriage to one man and one woman, FOX News projects.

Voters in different states also weighed in on hot-button issues such as marijuana legalization (search), stem cell research (search) and property tax caps.
