Tommy made mistakes that seems clear.
Just because someone is passionate about an issue, doesn’t make them a good politician.
For EU elections they use regional constituencies. Robinson ran in North West England, which elects 8 members. They use party list proportional representation, you vote for the party and if they get say 50%, they’d get 4 seats.
To have gotten elected as an Indie, Robinson would have needed at least about 8% they said. Doesn’t look like not running with UKIP made a difference though, UKIP got 3.6% and Robinson alone got 2.2% so enough combined they wouldn’t have cut it.
It’s unfortunate that Brexit Party and UKIP couldn’t reconcile.
