So, should the Republicans postpone or cancel their convention if this beast hits like it looks like it will?
No.
The convention has been lined up for months. People have taken off work, booked hotel rooms, bought plane rides, rented cars, etc. The GOP has rented facilities, brought in entertainers, scheduled media, etc. To move the event would cost tens of thousands of dollars - if not millions - and that assuming that the facilities are even available a week later.
Furthermore, if this hurricane hits hard, what good would it do to postpone a week? The stricken areas will still be in turmoil and the GOP would still be hammered for celebrating during a tragedy. And the GOP can’t postpone it much more… there’s a general election to worry about.
Hurricanes, tornadoes, earthquakes, fires, etc. hit this nation all the time. They shouldn’t be allowed to interfere with our selection of a new President. The GOP should be mindful of such events, release speakers and delegates from those areas to deal with it, and be respectful of the victims, but not let a hurricane detract from having as much of a good time as the Democrats did. Conventions have become pep rallies (much to my regret), but the GOP has every right to have one as much as the Dems.
