WASHINGTON (AP) — Four years ago, undecided voters’ late decisions to support Donald Trump helped push him to victory. While there are fewer on-the-fence voters this time around, a small but potentially significant group of people say they remain truly undecided less than three weeks before the Nov. 3 election. Some are still wrestling with what they see as a choice between two lousy candidates. Many of them are turned off by Trump’s personality and by Democrat Joe Biden’s policies. Some voted for third-party candidates in 2016 because they were so repelled by their choices in that race and may do so again this year. Both campaigns are trying to win them over.
