Be warned that Marco Rubio also supports lowering the broadband standard, and is against net neutrality.
Anything less than 25/5 (and no scumsucking usage cap!) is like having to crawl across a swaying rope bridge on an Interstate Highway.
I've been on 25/5 and on 3/1 and really can't tell much difference because most stuff is oversold to be barely tolerable. I would have no problem with them coming to some reasonable middle ground if they could figure out how to solve the oversold problem**. I currently work from home and I'm on a middle tier package which works fine during the work day but evenings it is barely usable and I've actually had to call in sick on days when the local school district has a snow day because all the neighbor kids are home and using the internet.
** The oversold problem is fixable if they want it to be. Just like fractional reserve banking or landline phones, you require a certain reserve and you build out for peak demand. Yes, this means that you're running at 50% capacity most of the time but then your service is actually usable during peak times. You can also use education, software, and incentives to try to get certain heavy non time critical downloads to happen during times where bandwidth is virtually free.
