The rules for the state-by-state vote for the electoral college are not part of the constitution, for example. Nor is crooked gerrymandering. Fixing those would be a great start. Automatic voter registration, making Election Day a national holiday, and prosecuting all of the corrupt officials who have been working together to suppress non-white votes would be good too. Abolishing the senate will take longer, for sure, but in the mean time we can stop cruelly disenfranchising the residents of Washington, D. C. and Puerto Rico, which I'm sure would have a positive effect on bringing the senate closer to the national electorate. Look up the National Popular Vote Compact. Some of these solutions are not as difficult as you'd imagine.
