Please read HR1, it will change your mind. A "republic" means you have a representative. It does not necessary mean a "democracy" where the citizens vote. In our case, the U.S. Constitution forms a democratic republic, where citizens elect their representatives, who in turn do the actual voting on laws, policies, etc. So the U.S. is a Republic, which is why the Constitution consistently refers to the U.S. as a Republic. There are subtle differences but people often mix the two.
Specifically with HR1, if our past election was fair and free from fraud, then why is there a need to change the election process to "secure the right to vote". Since only citizens have the right to vote and they can all vote, there's nothing that needs to be "secure". If you read HR1, you will find that it allows for online registration, which is extremely unsecure.
