Tuesday is the last day to register to vote in Colorado for the Nov. 6 general election, a contest that will pick the nation’s next president and determine the outcome of seven congressional races and the balance of power at the statehouse.

Colorado residents who are U.S. citizens still can register by going online at govotecolorado.com or in person at their county clerk’s office.

Voters on the state’s permanent mail ballot list will receive a ballot in the mail as long as they voted in 2010. Those who want a mail ballot have until Oct. 30 to go to govotecolorado.com and request one be mailed to them.

Voters who don’t cast ballots by mail can vote in person early starting Oct. 22 by going to a vote center.

Those who want to vote on Election Day, Nov. 6, will vote at either an assigned polling place or, in some counties, a vote center.

Coloradans also will consider three state ballot issues: legalizing pot, reforming the state’s personnel system and directing Congress to overturn a U.S. Supreme Court decision on campaign finance.
