Races in Missouri remain close on this Super Tuesday, with no clear winner on either the Republican or Democrat ballot even late in the evening.

Former Arkansas Governor Mike Huckabee had held a lead throughout the evening in the Republican primary, until Arizona Senator John McCain caught and passed him. With just over 300 precincts yet to report, McCain has 176,058 votes, 32.7% of the vote. Huckabee has 174,338 votes, just behind McCain with 32.3% of the vote. Former Massachusetts Governor Mitt Romney is running a close third with 155,112 votes, 28.8%. Texas Congressman Ron Paul is far back, garnering only 24,024 votes, 4.5%.

New York Senator Hillary Clinton had a sizeable lead early in Missouri, but has seen that lead slip. Clinton still holds the lead. She has 352,021 votes, 49.5% of the Democratic vote. Illinois Senator Barack Obama has 337,556 votes, just behind Clinton with 47.5% of the vote. Former North Carolina Senator John Edwards, who dropped out of the race after campaigning in Missouri, still received 15,441 votes, 2.2%.

Former Massachusetts Gov. Mitt Romney pledged to fight all the way to the Republican nominating convention this summer if necessary, despite being overpowered by John McCain in Super Tuesday contests.

The lion's share of Alaska's Democratic delegates will go to Barack Obama, who won the state's caucuses. Meanwhile, Mitt Romney scored a large victory over his competitors in the Republican preference polls.

The polls have closed in Missouri with a close race expected in both the Republican and Democratic primaries.

On the Democrat side, it appeared New York Senator Hillary Clinton had a strong lead in Missouri, but her rival, Illinois Senator Barack Obama, has closed the gap and some public opinion polls have Obama ahead of Clinton in Missouri.

Rasmussen public opinion poll released Saturday, conducted on Thursday, and had Clinton leading 47 to 38 against Obama. That poll, though, gave Edwards 11-percent.  It will be interesting to see where those supporters go since Edwards dropped out of the race after visiting Missouri.

With 815 of 3,371 precincts reporting, Clinton has 58.3% of the vote. Obama has 37%.

Republicans in Missouri seem a bit conflicted. Former Arkansas Governor Mike Huckabee had a lead for a time, but the momentum that Arizona Senator John McCain has been building has helped his popularity here. Former Massachusetts Governor Mitt Romney has the backing of Governor Matt Blunt, but has been lagging in the polls.

That same poll has McCain on top with 32%. Huckabee and Romney nearly tied; 29% for Huckabee and 28% for Romney. Texas Congressman Ron Paul comes in a distant fourth with only 5% of the vote.

Also with 815 precincts reporting, Huckabee has 37% of the vote, followed by McCain with 30.9% and Romney 25.2%. Paul trails the pack with 4.5%.

Up for grabs tonight on the Democratic side is 88 delegates to the Democratic National Convention. Of those, 72 delegates will be chosen tonight through proportional representation; 25 statewide and 47 from the nine Congressional districts. For Republicans; 58 delegates to the Republican National Convention and all 58 go to the winner, an important difference in how the two parties operate. Democrats will distribute delegates proportionally. Republicans give them all to the winner.
