AUGUSTA, Maine (Gambling911.com) - What's been a dead heat for the past few months suddenly is showing signs of a breakout favorite as the US Midterm races come down to the wire. Democrat Troy Jackson was just made a -300 favorite to win the Maine Senate race at BetOnline.
Jackson had been a slight favorite for the last several weeks over Republican incumbent Susan Collins since he entered the race. Collins now pays out $240 for every $100 bet should she be re-elected.
One of the primary reasons for the odds shift likely has to do with the latest poll numbers.
A final New York Times/Siena poll shows Democratic U.S. Senate candidate Jackson leading Collins in Maine by six points. It's the largest lead Jackson has held over Collins in a New York Times poll since entering the race in July.
The poll was conducted between Oct. 27 and Nov. 1.
BetOnline just released a series of Midterm prop bets on Monday.
