In the final days of the campaign, Democratic presidential hopeful Barack Obama will be working to help his party gain a super majority in Congress.

Obama is planning radio ads for Democrats in tight races, focusing particularly on helping Senate candidates.

Analysts say it's possible Democrats could reach 60 seats in the Senate, which would keep Republicans from blocking Democratic legislation.

Some Democrats have asked Obama to use portions of his record-high contributions for their races.

But the Obama campaign says the presidential race is too close for them to share that money.
