I believe there should be a second look at votes counted this year in the primaries. More oversight is never a bad thing and some states such as Nevada have done a very bad job running their primaries. Other states, like MN, CA, and more had such an unexpectedly high turnout polling places struggled to serve them all. Not only should the votes be looked at extra closely this year, but the entire primary system should be revised for greater voter confidence and convenience.
The Democratic Primary race has had some very close results in a few states. Many feel like the primary process is rigged because of archaic voter registration rules that several states impose. Also, the Iowa Democratic Party Caucus had razor-thin results; many feel Hillary may have stolen the Caucus. There are other voter complaints in several states as well. In short, it would not hurt to take a second look at the primary votes counted this year.
Every time there is a hot and highly contested election, there are cries of voter fraud and incorrectly counted ballots. A recount will not provide the losing candidate an edge, especially in the instance of millions of votes. When the top candidate is a few MILLION votes ahead, there is no need to waste time with a recount.
No, there should not be a second look at the votes counted this year in primaries. There is no reason to believe that the votes have been counted incorrectly. Therefore, there is no need for a second look at the votes. People should trust the American voting system. In the absence of corruption, there is no reason to believe that the vote count was inaccurate.
