According to Rasmussen Reports, the race for Senate in South Dakota as Senate Minority Leader Tom Daschle desperately seeks reelection is once again effectively tied, though the poll shows a small lead for challenger John Thune. Here's what Rasmussen writes:

In his bid for re-election, Senate Minority Leader Tom Daschle has fallen slightly behind former Congressman John Thune.

The latest Rasmussen Reports survey finds the Republican challenger earning 50% of the vote while Daschle attracts 47%. However, the 3-point advantage for Thune is well within the survey's 4.5 point margin of sampling error.

Rasmussen also shows Democratic Congresswoman Stephanie Herseth ahead by the same margin for the statewide seat, but like the Senate poll, the race is effectively tied due to the MoE.

Though this polling is somewhat different than an earlier internal poll for Daschle showing the Democrat leading, it's safe to say that this race will remain tight throughout the remainder of the campaign season and we might not know who actually won until after election night (remember Thune lost two years ago to Senator Tim Johnson, but we didn't find that out until the next morning). If you can (and want to), you should go to Daschle's website to give what you can to ensure the Democrats win back the Senate (there are also links to other races you might consider supporting on the right).
