Yes there is usually enough time during endorsement campaigns.
You can put the application in the mail Monday and I will receive it by Friday. I will call you on the weekend for the name of your favorite candidate. Your endorsement might be shown in next week’s email message, Facebook and Twitter posts. It will be shown if there are enough new members to trigger another round of endorsement votes.
Depending on the latest vote count, one new member may be enough to launch the next round of endorsement voting.
