It's actually a very poor excuse not to bother to vote at all, which is extremely foolish when your ballot has other things to vote on.  California suffered greatly from this last November, as both their idiotic primary system and the foregone Hillary win discouraged voter participation.  This enabled some extreme ballot propositions to be passed.  I knew that my choice for President had no chance of winning, but I still voted because of other matters on the ballot that will affect this state long after 2020.

I think a proportional allocation system would be beneficial to voter participation and turnout.  It will never happen in states like California, New York, and Texas who need it most, but are strongholds for one political party who will not dream of letting go of a single electoral vote in the interest of fairness and increasing voter participation.
