If statement skips first condition

I am trying to make a virtual voting booth that accepts the user id encrypts it, verifies and validates voter id, then checks if the voter has already voted. But it skips the first condition. I'm not an expert programmer. I'm new and just learning python. I need your help! Thank you in advance for your expertise!

These are the steps:

1. Step 1: Voter generates a pair of private and public keys – for the purpose of digital signature. Voter uses his private key to sign his request and the public key of the CLA to send his/her message. The message must include the voter’s signed id, say, SSN (request) and the voter’s public key. The public keys of the CLA and CTF may be passed to a voter when he/she starts the session.

2. Step 2: CLA reads the message sent on Step 1 using its private key and, using the voter’ public key, finds the voter’s id . CLA encrypts the validation number using its private key and sends it to the voter. The voter finds the validation number, using the public key of the CLA.

3. Step 3: The CLA sends the list of validation numbers to the CTF using a symmetric key negotiated between CLA and CTF.

4. Step 4: The message from the user to the CTF must be encrypted using the public key of CTF.

The result show this:

Welcome to the Vitrual Election Booth.

Enter your voter id:1234

You have already voted! Thank you!
