Liberals worried about getting people to the polls on time?

NY Times:

Measures by G.O.P. Aim to Limit Voting in Swing States

The bills, laws and administrative rules — some of them tried before — shake up fundamental components of state election systems, including the days and times polls are open and voting locations.

This is a weird argument.  Elections have always been on a specific day during specific  times.  In recent years there have been times set aside for absentee balloting.  Reducing the time period should be of little inconvenience to almost all voters since there is still more than adequate time to vote if you can't vote on election day.  There have been abuses of the absentee ballot that have resulted in vote fraud.  There are very recent cases of that happening in Texas in local elections.  Almost always it is the Democrats engaged in the vote thefts.

What the liberals seem concerned about is a process that will make it harder for them to cheat.  To them cheating to get Democrat elected is a right.  Recently a woman convicted of voting for Obama six times in the same election was celebrated by Democrats when she was released from her jail sentence.  That suggest at a minimum that Democrats don't have a high regard for voter integrity.  If they were really serious about voter integrity I might be willing to consider their complaints.  Instead they are dismissive and that is why I don't take this complaint seriously.

What does this concern about the Democrats' attitude about the intelligence of their own voters think can't show up and vote at the designated times but they believe Republican voters are smart enough to do so?  Why do they hold their voters in such low regard?
