Republicans and Democrats are making a final push for votes as polls show some races tightening in the US mid-term elections. As President George W. Bush continues on the campaign trail, new opinion polls show his Republicans gaining ground in a number of key Senate races.
But rival Democrats are still positioned to make gains in the Senate and recapture control of the House of Representatives for the first time since 1994. All 435 House seats, a third of the Senate and 36 governorships are up for grabs in Tuesday’s voting. The Democrats need to pick up 15 seats in the House and six in the Senate to claim majorities and take control of each chamber.
