Am I missing something here?: I thought that Democrats were supposed to get upset with anything that increased the cost of voting

From John Fund at the WSJ.com's Political Diary:

[Clinton] is scrambling for every possible advantage -- down to having her supporters file lawsuits to close some poling places -- in Nevada's Democratic caucus this coming Saturday.

How is this consistent with Democrat Party rhetoric on voting? We can't even have voter IDs because they might discourage people from voting.
